This is a complete list of the variables that are currently used inside &Aap;, except the variables specifically used for porting, see for that. This list will be extended when more features are being added. To avoid the problem that your own variables interfere with the use of common &Aap; variables, do not use variable names with only upper case letters. Suggested scheme: $STANDARD_VARIABLE global variable defined by &Aap; $YourVariable global variable used in your recipe(s) $local_variable local variable used in build commands The following table lists the predefined variables. These types are used: &Aap; set by &Aap; and mostly not changed by the user conf set depending on the configuration of the system, may be modified by the user user set by the user auto value updated when using commands (e.g., :program), may also be appended to by the user name type   description $# &Aap; A single #. OBSOLETE, use $(#) $$ &Aap; A single $. OBSOLETE, use $($) $AAP &Aap; Command that was used to start &Aap;, including the Python interpreter used. Example: :asroot $AAP install Note that this can be a command and an argument, e.g.: "/usr/local/bin/python1.5 /usr/local/share/aap/Main.py". $AAPSYSDIR conf List of system directories to search for startup recipes, modules and tools. Default value is /usr/local/share/aap, although this may be different on some systems. When the directory doesn't exist the default is empty. $AAPVERSION &Aap; Version number of &Aap;. E.g., 31 (version 0.031) or 1003 (version 1.003). Also see $VERSIONSTR. $AR conf Name of archiver program: combines object files into a static libray. $ARFLAGS user Arguments for $AR (default: "r" or "/nologo"). $BDIR conf Directory to write build files in. Modified by the :variant command. $BR &Aap; A line break. $BROWSER conf HTML browser to be used for the "view" action for HTML, XML and PHP files. The default value comes from the "BROWSER" environment variable or a list of known browser commands (netscape mozilla konquerer grail iexplore mosaic lynx w3m). $BUILD_ACTION conf When not empty, specifies the action name to be executed for building. Usually for building a program from object files with a specific tool. A "buildaction" attribute on one of the object files is used before $BUILD_ACTION. See . $BUILDDLL_ACTION conf When not empty, specifies the action name to be executed for building a dynamic (shared) library. A "buildaction" attribute on one of the object files should be respected by the action specified with $BUILDDLL_ACTION. See . $BUILDLIB_ACTION conf When not empty, specifies the action name to be executed for building a static library. A "buildaction" attribute on one of the object files should be respected by the action specified with $BUILDLIB_ACTION. See . $BUNZIP2 conf Program to use for ".bz2" compressed files. Default value is "bunzip2". $C_COMPILE_ACTION conf When not empty, specifies the action name to be executed for compiling a C file into an object, dllobject, libobject or ltobject file. See . $CXX_COMPILE_ACTION conf When not empty, specifies the action name to be executed for compiling a C++ file into an object, dllobject, libobject or ltobject file. See . $CACHEPATH conf List of directories to search for cached downloaded files. Default for Unix: /var/aap/cache ~/.aap/cache aap/cache For MS-Windows, OS/2: $HOME/aap/cache aap/cache Directories that don't exist are skipped. When using a relative name, it is relative to the current recipe. Thus the recipe specified with :child dir/main.aap uses a different cache directory. When this variable is set, currently cached files are flushed. Otherwise this only happens when exiting. Thus this command can be used to flush the cache: CACHEPATH = $CACHEPATH $CACHEUPDATE user Timeout after which cached files may be downloaded again. For the possible values see the explanation in the user manual. $CC conf Command to execute the C compiler (default: "cc"). $CFLAGS user Arguments always used for $CC. NOTE: it's not $CCFLAGS! This is inconsistent, used for historic reasons. $CHILDDIR &Aap; In a child recipe: The directory of the child recipe relative to the parent recipe. When using: :child subdir/main.aap $CHILDDIR will be "subdir" in the child recipe. $CLEANDIRS auto Names of directories that the "clean" target should remove. $CLEANFILES auto Names of files that the "clean" target should remove. The :program command adds files to this. $CLEANMOREDIRS user Names of directories that the "cleanmore" target should remove. $CLEANMOREFILES user Names of files that the "cleanmore" target should remove. $COMPILE_ACTION conf Obsolete.

When not set $CVS is used. $CXX conf Command for compiling C++ files $CXXFLAGS user Arguments always used for $CXX. $CXXSHLINK conf Name of linker used to combine object files from C++ sources into a shared (dynamic) library. Default value: "$CXX" for Unix, not used for MS-Windows. $CXXSHLINKFLAGS user Arguments for $CXXSHLINK.

Used in the same place as $CPPFLAGS. Form: "-DNAME" or "-DNAME=value". The tools will convert this to the argument the compiler actually uses. $DESTDIR user Directory used to install in a different root directory. Useful for a "fake" install. Also see $PREFIX. $DISTDIRS &Aap; Names of directories that should be distributed as a whole. If there is one file in this directory that should not be distributed use $DISTFILES. $DISTFILES auto Names of files that are used as a source in the recipe and should be distributed. The :program command adds files to this. $DLLCFLAGS user Extra arguments to compile a C program into a dynamic (shared) object file. The default is currently "-fPIC", but since that only works with gcc it will soon be changed. $DLLCXXFLAGS user Extra arguments to compile a C++ program into a dynamic (shared) object file.

Also see $TIMESTR and $DATESTR. $GROUPCOUNT &Aap; Number of files handled at a time for uploading, downloading and version control commands. The default value is 20. Set it to a smaller number when using big files. Set it to a large number when you need to enter a password every time. $HASGCC conf Indicates whether gcc can be used to scan C sources for dependencies. It is initialized empty. When dependency scanning is to be done a configure check is run to see if $CC can be used for dependency checking. $HASGCC is then set to "yes" or "no". You can set $HASGCC to empty to force running the check again, set it to "no" to avoid using $CC for dependency checking or set it to "yes" to skip the configure check and use $CC for dependency checking. $HASGCCXX conf Indicates whether gcc can be used to scan C++ sources for dependencies. Just like $HASGCC does this for C. $INCLUDE user Directories to find include files. Used in the same place as $CPPFLAGS. Form: "-Ipath".
